Filed: 1949-04-22
Abstract: 664,621. Magazine gramophones. THORENS SOC. ANON., H. April 22, 1949. [April 22, 1948] No. 10762/49. Class 40 (ii). In a gramophone having record changing means operated by a wheel 53, meshing with a pinion 52 on the turn table spindle 11 and having a sector 113 with displaced teeth in which pinion 52 idles during actual playing of the record, the wheel 53 and pinion 52 are brought into active engagement by an eccentric latch member 51 which rotates with the spindle 11 and engages an arm of bell crank lever 108 pivoted on wheel 53 if this lever has been sufficiently moved by a lever 106 rotating on a pivot 40 and moved by connection with the pick-up arm. Lever 106 is connected to a fork 107a and 107b by a frictional coupling and the fork encloses a pin 109 on the tone arm. The break 119 of lever 108 is thus slowly brought nearer to the path of latch 51 but at normal speeds the members do not couple and the lever 108 is pushed back and the friction connection of fork 107a slips. When the needle reaches the rapid pitch groove at the centre, however, lever 108 is sufficiently moved to be hooked by catch 51 and the wheel' 53 is dragged into engagement with pinion 52. A spring blade 110 restores lever 108 to its initial position in the second half rotation of wheel 53. The restoration of the pick-up arm to its original position also restores lever 106 .to its original position against an abutment. The records are carried on an extension of rod 11 and are lowered into position by mechanism described in Specification 664,619. The pick-up is moved by an extension cooperating with wheel 53 also as described in this Specification.

Stop-gear. - A fluid pressure governor with servo-motor transmission is controlled by the pressure derived from an oil-pump 15 driven by the prime mover through a shaft 17. The pump delivery 18 communicates through a pipe 22<1> with a pressure-responsive device comprising an adjustable spring-controlled piston 61 sliding in a cylinder 60 and controlling through the linkages shown the supply valve 46 of a servomotor 24, 23 adapted to open and close the main supply valve 12. A check valve 113 is inserted in the pipe 22<1> to prevent hunting. A stop-gear operating in conjunction with the governor through the same relay, comprises a cylinder 80 with a plunger 81 in communication with the pressure steam in the supply main, release of which to the atmosphere takes place by a pipe 84 and valve 87 controlled by an emergency governor 90 on the shaft 17 through trip levers 89, 88. This release results in a downward motion of the piston 81 whereby the relay valve 46 is lowered and the main valve closed by the relay piston 24, which is further assisted in its operation, should the oil pressure fail, by the piston 81 through a lever 51 pivoted to an extension 26 of the relay piston-rod 25, the motion of the valve being limited by a collar 47. To prevent interference between the pressureresponsive piston 61 and the stop-gear, both of which operate the relay through the lever 51, lostmotion devices 96, 97 and 100, 101 are provided. For starting purposes the pump delivery 18, provided with a check valve 112, has an auxiliary connection 110, with check valve 111, communicating with a supply of oil under pressure, such as the bearing supply. Exhaust oil from the relay is returned to the pump by a pipe 19 and any leakage is supplied from the overflow of a thrust bearing by a pipe 20. To ensure free operation of the piston 61 it slides on an extension 70 of the cylinder head 69 and is provided with a ball-jointed connecting-rod end 76, 62, while the pressure of the spring 65 is transmitted through gimbal rings 73, 74. A leak-off conduit 77 is provided at the top of the cylinder, which together with conduits from the ends of the relay valve and piston gland communicate with a sump.
